Hi all,
I want to transmit a file through tx_ofdm.grc model and receive it in
using rx_ofdm.grc. Presently this simulation takes in a vector source of
packet length as input and it creates tags for it.
I am able to receive these vectors correctly using rx_ofdm.grc
Now I want to send file as data but I dont find any block which adds
tags to file.
Alternately, can someone suggest the method of converting the file
content into vectors of packet length configurable by the user so that
it can be entered into the vector source.

Hi Ashish,
and first of all, thanks for testing the OFDM codes.
Now I want to send file as data but I dont find any block which adds tags to
file.

vectors of packet length configurable by the user so that it can be entered

There’s no simple way to do this, which I believe is an omission. I’ve
created http://gnuradio.org/redmine/issues/603 and will add a block
soon.
Until then, you’ll have to load the block into an array, split that into
manageable chunks and pass all of them as tagged streams to the
vector_source (in Python land).
Cheers,
MB

Can you please try this:
